トラクタ等移動農機のパワーステアリング装置。 A power steering device for a mobile agricultural machine such as a tractor, which comprises a power steering unit that controls the amount of pressure oil from a hydraulic pump in response to the rotation of the steering wheel, and a steering mechanism that steers the steered wheels using the pressure oil sent from the power steering unit. In this, the above-mentioned steering mechanism is provided with a steering angle sensor that monitors the steering state in conjunction with the rotational operation of the steering wheel, and an intermediate portion of the oil supply from the hydraulic pump to the power steering unit is provided with a sensor that controls the pressure state of the pumped oil. 1. A power steering device for a mobile agricultural machine such as a tractor, characterized in that a steering hydraulic pressure control section is provided to control the hydraulic operation of a steering mechanism in conjunction with the steering monitoring state of the steering angle sensor.
